From neutron diffraction measurements on a quasi-1D Ising-like Co$$^{2+}$$ spin compound BaCo$$_2$$V$$_2$$O$$_8$$, we observed an appearance of a novel type of incommensurate ordering in magnetic fields. This ordering is essentially different from the N$'e$el-type ordering, which is expected for the classical system, and the peculiar spin structure is caused by quantum fluctuation inherent in the quantum spin chain. A Tomonaga-Luttinger liquid (TLL) nature characteristic of the gapless quantum 1D system is responsible for the realization of the incommensurate ordering.
